ACOUSTIC MONITORING METHOD FOR OPERATION STATUS OF VERY LARGE FLOATING PLATFORM

An acoustic monitoring method for the operation status of a very large floating platform (1), appliable to a system for monitoring the operation status of the floating platform (1), the system comprising the platform (1), seabed depth acoustic measurers (2), sea surface height acoustic measurers (4), a seabed sediment acoustic measurer (6), and an attitude measurement sensor (8). The method comprises: controlling the attitude measurement sensor (8) to measure the platform (1) to obtain absolute attitude data; control the sea surface height acoustic measurers (4) to measure the sea surface to obtain sea surface status data; controlling the seabed depth acoustic measurers (2) to measure the seabed to obtain seabed status data; controlling the seabed sediment acoustic measurer (6) to measure the seabed to obtain seabed stratification and sediment type data; and constructing operation status data on the basis of the absolute attitude data, the sea surface status data, the seabed status data, and the seabed strati
